994 \class QGridLayout-
995-
996 \brief The QGridLayout class lays out widgets in a grid.-
997-
998 \ingroup geomanagement-
999 \inmodule QtWidgets-
1000-
1001 QGridLayout takes the space made available to it (by its parent-
1002 layout or by the parentWidget()), divides it up into rows and-
1003 columns, and puts each widget it manages into the correct cell.-
1004-
1005 Columns and rows behave identically; we will discuss columns, but-
1006 there are equivalent functions for rows.-
1007-
1008 Each column has a minimum width and a stretch factor. The minimum-
1009 width is the greatest of that set using setColumnMinimumWidth() and the-
1010 minimum width of each widget in that column. The stretch factor is-
1011 set using setColumnStretch() and determines how much of the available-
1012 space the column will get over and above its necessary minimum.-
1013-
1014 Normally, each managed widget or layout is put into a cell of its-
1015 own using addWidget(). It is also possible for a widget to occupy-
1016 multiple cells using the row and column spanning overloads of-
1017 addItem() and addWidget(). If you do this, QGridLayout will guess-
1018 how to distribute the size over the columns/rows (based on the-
1019 stretch factors).-
1020-
1021 To remove a widget from a layout, call removeWidget(). Calling-
1022 QWidget::hide() on a widget also effectively removes the widget-
1023 from the layout until QWidget::show() is called.-
1024-
1025 This illustration shows a fragment of a dialog with a five-column,-
1026 three-row grid (the grid is shown overlaid in magenta):-
1027-
1028 \image gridlayout.png A grid layout-
1029-
1030 Columns 0, 2 and 4 in this dialog fragment are made up of a-
1031 QLabel, a QLineEdit, and a QListBox. Columns 1 and 3 are-
1032 placeholders made with setColumnMinimumWidth(). Row 0 consists of three-
1033 QLabel objects, row 1 of three QLineEdit objects and row 2 of-
1034 three QListBox objects. We used placeholder columns (1 and 3) to-
1035 get the right amount of space between the columns.-
1036-
1037 Note that the columns and rows are not equally wide or tall. If-
1038 you want two columns to have the same width, you must set their-
1039 minimum widths and stretch factors to be the same yourself. You do-
1040 this using setColumnMinimumWidth() and setColumnStretch().-
1041-
1042 If the QGridLayout is not the top-level layout (i.e. does not-
1043 manage all of the widget's area and children), you must add it to-
1044 its parent layout when you create it, but before you do anything-
1045 with it. The normal way to add a layout is by calling-
1046 addLayout() on the parent layout.-
1047-
1048 Once you have added your layout you can start putting widgets and-
1049 other layouts into the cells of your grid layout using-
1050 addWidget(), addItem(), and addLayout().-
1051-
1052 QGridLayout also includes two margin widths:-
1053 the \l{getContentsMargins()}{contents margin} and the spacing().-
1054 The contents margin is the width of the reserved space along each-
1055 of the QGridLayout's four sides. The spacing() is the width of the-
1056 automatically allocated spacing between neighboring boxes.-
1057-
1058 The default contents margin values are provided by the-
1059 \l{QStyle::pixelMetric()}{style}. The default value Qt styles specify-
1060 is 9 for child widgets and 11 for windows. The spacing defaults to the same as-
1061 the margin width for a top-level layout, or to the same as the-
1062 parent layout.-
